Batch PhotoTools — Changelog

Batch PhotoBrowser started slowly and ignored clicks for up to several minutes. Right after launch, the app silently burned a full CPU core and up to ~2 GB of memory for 30 seconds to several minutes. During that time the Browse button did nothing, and folders passed from the Explorer context menu or from Batch Geolocate's "Show Photos" could fail to open. The cause was the UI framework endlessly exploring an infinite chain of Windows UI properties at startup. Now the app starts instantly and Browse responds immediately.

Web streamer follows the sort order chosen in PhotoBrowser, adds an Images/Videos filter, and supports "play from here" in the slideshow.
Web streamer lightbox supports touch swipe (previous/next) on mobile.
Web streamer shows the launch folder itself (whole subtree), not just its subfolders.
PhotoBrowser slideshow plays videos full-screen instead of showing a static poster frame.
Assorted slideshow and sort refinements in both PhotoBrowser and the Web streamer.

Cast to TV works again. Version 1.4.4 shipped with a broken network-discovery component, which made casting fail with a misleading "pychromecast not installed" message.

Batch PhotoBrowser could crash on startup due to a splash screen error.
AI Analysis window made the whole PC sluggish — image decoding and zoom animations were reworked (~11× faster per image).
Launching companion apps from each other could fail regardless of install folder name.
